Hopefully when the launch takes place later today, users won’t encounter any major bugs. Apple has reportedly shipped the pre-release build of OS X 10.8.5 to a selected group of partners, this is seen as an indication that the public release isn’t too far off.

The update is also said to improve AFP file transfer performance over 802.11ac Wi-Fi. Apart from improving Xsan reliability, this latest update will reportedly solve an issues that may prevent a screensaver from starting automatically.

No official word has been received from Apple as yet regarding this update. The last beta version was shipped to developers on July 31st.
